Cryogenic treatment is a process that aims to modify the microstructures of metallic materials at ultra-low temperature in order to improve their properties. It has been classified into two categories, i.e. deep cryogenic treatment (DCT) and shallow cryogenic treatment (SCT) [1, 2]. As a most studied cryogenic treatment process, DCT is ...
In our industry this has led to some problems, as heat treaters tend to call the -110ºF cold treatment to convert retained austenite to martensite a cryogenic treatment. It is not cryogenic, and it does not do the same thing. Since there is no official definition of the process, the process parameters vary widely from one company to the next ...

The use of cryogenic treatment (CT) to improve mechanical properties of materials has been developed from the end of the Sixties. At the present time, the initial mistrust about CT has been cleared up and many papers about differ- ent materials reporting laboratory tests results, microstructural investigations and hypothesis on CT …
A typical cryogenic treatment or deep cryogenic treatment (DCT) [11, 12] consists of cooling down as low as possible from ambient temperature, soaking the components at a relatively low temperature approximately at −196 °C [14–17], maintaining at this temperature for an appropriate time (generally ∼24–36 h) and then warming up …
Thus, most of the resulting 14 recommendations are based on studies that included outcomes for recurrence rates of CIN, major and minor adverse events, and cervical …

The influence of deep cryogenic treatment on the microstructure and properties of AlCrFe 2 Ni 2 high-entropy alloy were studied by examining its phase composition, microstructure, and properties after cryogenic treatment. The results showed that as the cryogenic treatment increased, the alloy was composed of face-centered …
Typical cryogenic treatment consists of a slow cool-down of -5 °F per minute (-3°C per minute) from ambient to -320 °F (-196°C), a soak for 24 to 72 hours, and warm up to ambient temperature. The cryogenically treated parts are then subjected to a temper treatment (300 to 1000°F or 149 °C to 538 °C) for a minimum of one hour. ...

Cryogenic Treatment is a process that strengthens and improves the mechanical properties of metal materials. The material is exposed to a subzero temperature, as cold as -300ºF, reducing the amount of retained austenite and transforming it to a martensitic state. Cryogenic treatment results in increased strength, dimensional stability, and ...
The XRD patterns of the Al 1.4 CrFe 2 Ni 2 HEAs under as-cast and different cryogenic treatment time are obtained as shown in Fig. 1.The results show that the phase structure of Al 1.4 CrFe 2 Ni 2 HEAs with cryogenic treatment are both disordered BCC (A2) and ordered BCC (B2). The A2 phase is rich in (Fe, Cr) and the B2 phase is rich in …
Thermal processing for metals is nothing new. Heat treating has been used for centuries to alter metals' characteristics. Although the simplest heat treatment comprises just three steps—bringing the metal to a specified temperature, holding the temperature for a set length of time, and bringing it back to room temperature, in a …
Cryogenic treatment does not take the place of heat treatment, rather, it completes what the heat treater started. When heat treating, the temperature is increased to the proper "high" temperature for the type of metal being treated. At the correct time, the parts being heat-treated are put in "the quench," at which time the temperature ...
